Wouldnt u add all those amounts of money then divide it by 40 so it would give u the amount of money needed to cover her costs?
(4.55 x 10^13)-(1.78 x 10^12)=4.372 x 10^13
45500000000000
- 1780000000000
-----------------------------
43720000000000 or 4.372 x 10^13
Given:
Cost of bracelet without charm - $85
cost of each charm - $15
Function notation: f(x) = 15x + 85
The price of the bracelet depends on the number of charms they will buy. x represents the number of charms they will buy.
The reasonable domain for this function is at least 1. They must buy at least 1 charm because they intend to buy their mom a silver charm bracelet.
If their budget is 250
250 = 15x + 85
250 - 85 = 15x
165 = 15x
165/15 = x
11 = x
They can buy at most 11 charms without going beyond their budget.

<u>Answer:</u>
The Time taken by Elena and Jade to meet up is 2.5 hours
<u>Explanation:</u>
Given,
Elena moves with a speed of 6mph while Jada walks at a speed of 4 mph
Also, Distance can be calculated by the formula

To find out the Total speed, i.e., speed of both Elena and Jada as both of them are walking in opposite direction we should add the speed of both the persons, if in same direction we should subtract the values
Here it will be:
= 10mph
Distance apart is given as 25 miles. Substituting the values,

25 = 
Time = 25/10
Time = 2.5 hour
Hence, It will take 2.5 hours to meet up.
